Objective: To study the effect of berberine on the release of nitric oxide (NO) by rat intestinal mucous microvascular endothelial cells (RIMECs) cultured in vitro for exploring the pharmacological mechanism of berberine in treating intestinal disease.
Methods: Cultured RIMECs in vitro were identified adopting immunofluorescent stain with factor VIII-related antigen. NO level in the supernatant of normal cell culture or cell culture treated with different concentrations of berberine was detected with colorimetry at the 3rd, 6th, 9th and 12th h and compared.
Objective: To observe effect of electroacupuncture at "Zusanli" (ST 36) on expression of interferon-gamma (IFN-gamma)-like immunoreactive substance in spinal cord of the rat and to probe the mechanism.
Methods: The IFN-gamma-like immunoreactive positive cell number in spinal cord of the rat was investigated with immunohistochemical SP method and microscopy.
Results: After electroacupuncture at "Zusanli" (ST 36), IFN-gamma-like immunoreactive positive cell number in the spinal cord of the rat with electroacupuncture plus immunosuppression did not significantly change (P > 0.
